Frequently Asked Questions (FAQ)

Q: What makes MXH105K305H20 and MXT105K305H20 suitable substitutes for R46KR4100JEM1K?

A: Both substitute parts match the critical electrical parameters (1 µF capacitance, ±10% tolerance, 305V AC / 630V DC ratings) and mechanical specifications (radial configuration, 32.00mm x 11.00mm dimensions, 27.50mm lead spacing). All three parts are ROHS3 compliant and maintain Active product status.

Q: Are there differences between the two CDE substitute parts?

A: MXH105K305H20 and MXT105K305H20 differ in series designation (MXH vs. MXT) and packaging format (Bulk vs. Tray). Both parts are electrically and mechanically identical with matching voltage ratings, capacitance values, and dimensional specifications. The MXT series includes AEC-Q200 automotive rating, while the MXH series includes automotive application designation.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts share identical mechanical dimensions, lead spacing, and termination type (PC Pins), enabling direct substitution without PCB redesign or layout modification.

Q: What is the significance of the 305V AC and 630V DC ratings?

A: These ratings indicate the maximum voltage the capacitor can safely withstand. The 305V AC rating is typical for safety-rated EMI suppression applications, while the 630V DC rating provides margin for DC circuit applications. All substitute parts maintain these identical ratings.

Q: Are there any compliance considerations for substitution?

A: All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. ECCN classification (EAR99) is identical across all parts, confirming equivalent export control status.
